Six player games are rarely fun in my experience. Most of my group prefers to break into two games of three at that point. Four is sorta the ideal number, and five is doable, but six sucks.Quote from Dan_Fendi »I naively believed that our six person game would be fun
As for your question - Gaddock Teeg tends to shut down a lot of stuff people want to play. He also comes down early enough to make a difference. You can run Linvala, Keeper of Silence, Void Winnower, Brisela, Voice of Nightmares, Aven Mindcensor, Torpor Orb, etc. to shut down all the things they plan on doing.
